We finally have a progress report on the integration of the IR-LOCK (Infrared Pixy) vision sensor with Pixhawk. A group of students at the Georgia Institute of Technology is using the sensor for their 'Package Delivery Drone', which requires precision landings. They plan to use GPS to travel to a waypoint, and then use the IR-LOCK sensor to land precisely on an infrared beacon. Recently, they were able to get an IRIS+IR-LOCK to auto-hover over an IR beacon (see videos).
Other applications for IR-LOCK/Pixhawk are in the works (or at least in mind):
- Search&Rescue (auto-search for emergency IR beacons)
- Moving target following
- Aerial surveying (I will be able to post a relevant video soon)
- ... your thoughts/ideas are welcome :)
We are in the process of making the IR-LOCK/Pixhawk interface more developer-friendly. The current developments (by the student group) are based on an IR-LOCK sensor 'driver' and codebase discussed on this FAQ page (link). A 'more official' implementation should be under development soon. The relevant discussion is here (link).
Small IR 'Pods' can be detected by the IR-LOCK sensor at about ~30-60ft. The IR-LOCK sensor reports the (xy) position of IR targets to Pixhawk at 50Hz.
